Title: Vehicle seat belt with shock absorber - has spring loaded piston and restricted fluid flow for further absorber action
IPC: F16F13/02
Filed: 1974-10-16
Abstract: An outer casing (1) fixed to the vehicle has two chambers. The smaller diameter chamber (5) contains a piston (8) whose piston rod (10) passes through both chambers and outside the casing for attaching to the belt (14). The larger chamber (6) is filled with oil and has a piston (16) over the rod, forming a seal between the chambers. For normal use, a spring (23) around the rod in the lower chamber absorbs movement but a sudden shock compresses the spring against the larger piston and a spring catch (19, 20, 21) locks in a recess (24) in the piston rod to further belt forces move the pistons together. Oil passes from the upper chamber, through passages (26, 27) in the rod, into the lower chamber to provide further shock absorption.

Title: Standby power supply for central heating pump - uses battery invertor to prevent cut-off of gas supply
Inventor: DESVIGNES PHILIPPE
IPC: F04B49/06
Filed: 1974-12-20
Abstract: The standby power system for the circulation pump (2) of a central heating system (3, 4, 5) consists of a mains failure relay (10, 11, 12), a charger unit (9), a 12v battery (7) and a DC to AC invertor (13). Normally, the pump is driven by the mains and the battery receives a controlled charge. If the mains fails, then the relay switches the battery so that it is connected to the invertor and its output of 230v is connected to the pump motor. This system is intended for use in central heating systems where the pump stoppage causes the gas heating supply to be switched off, which is inconvenient during power failures.

Title: Ship yard crane crab travel mechanism - uses forces generated by load variations to move crab along jib
IPC: B66C23/26
Filed: 1974-12-26
Abstract: The mechanism moves the crap or a shipyard crane along the jib, without using any forces other than those generated by the variations in the loads lifted. There may be specially reeved ropes and pulleys moving the crab towards the jib head when under load, the crab (3) being pulled back towards the tower (10) by a counterweight (9) previously raised by the crab travelling outwards. There may be a drum with brake controlling the crab movement in both directions. The hoist rope (1) is reeved round the pulleys on crab and hoist block (4), and them round a further pulley (2) at the jib head to the anchor point, to effect the crab travel movement.

Title: Nickel extraction from laterite ores - using a two phase treatment with acid and basic magnesium carbonate
IPC: C22B3/00
Filed: 1975-02-25
Abstract: Extraction of nickel from laterite ores by acid leaching is improved by neutralising the products of backing in two stages, the first at up to pH 1.6-1.7 being effected in the leaching tank by injection of an aq. paste of treated serpentine, the second at pH 2.4-2.5 after sedimentation of this paste by adding an aq. paste of basic magnesium carbonate obtd. from the treatment of the serpentine to increase the nickel content and reduce the magnesium content. >94% of the Ni and 85% of the cobalt present in the serpentine can be extracted. The range of pH at which subsequent treatment of the remaining liquor can be effected is increased given that 80-90% of Al and Fe present are precipitated in the liquid part of the paste during the first neutralisation step. The final pH can be controlled by using a solid neutralising agent since the major part of the Fe and the Al have been first removed.
